feat(amazonq): auto-reject edit suggestions when cursor moves >25 lines away

[floralph]

Problem

Amazon Q edit suggestions remain active even when users navigate far away from the suggestion location, leading to confusion and potential unintended edits when users accept suggestions they can no longer see.

Solution

Added automatic rejection of edit suggestions when the cursor moves more than 25 lines away from the suggestion location. Implemented cursor change listener with proper cleanup to prevent memory leaks and ensure suggestions are only accepted when contextually relevant.
